按关键词mySQL搜索

Question

我正在尝试根据关键字查询表。我的表看起来像：

+------------+--------------+------+-----+---------+----------------+
| Field      | Type         | Null | Key | Default | Extra          |
+------------+--------------+------+-----+---------+----------------+
| id         | int(11)      | NO   | PRI | NULL    | auto_increment |
| username   | varchar(255) | YES  |     | NULL    |                |
| tweetBody  | varchar(255) | YES  |     | NULL    |                |
| datePosted | varchar(255) | YES  |     | NULL    |                |
| likes      | int(11)      | YES  |     | NULL    |                |
| dislikes   | int(11)      | YES  |     | NULL    |                |
+------------+--------------+------+-----+---------+----------------+

我正在尝试的查询看起来像

SELECT * FROM tweets WHERE tweetBody LIKE'is';

我试图找到包含该作品的所有推文＆＃39;是＆＃39;但是我没有得到任何结果。显然，我确实有包含的推文。这是我目前的表格：

+----+----------+----------------------------------------------------------------------------------------------------------------+------------+-------+----------+
| id | username | tweetBody                                                                                                      | datePosted | likes | dislikes |

Answer 1

您需要在like搜索

中添加通配符

SELECT * FROM tweets WHERE tweetBody LIKE '%is%';

  

％匹配任意数量的字符，即使是零字符   _只匹配一个字符。
